![]() Just happened the other day after having popper out the trigger plenty of times before.Īll the sliding pressure boundary crossing pins in previous pneumatic guns have been stainless steel, but because this pin is thicker than usual the Taiwanese have figured that they can substitute brass because here it is unlikely to bend. And yes, it's one of those "ask me how I know" deals. If you don't pull it forward, the rear end will still be inside the trigger cassette and will bend if you try to force the cassette out. It's cheap as chips in those small sizes anyways.īTW, if any of you are taking your trigger out of the handle for inspection, remember to pull the trigger transmission pin all the way forward first (the one that runs forward to interface with the trigger pin in your drawing above). I hope it is "just" pitting because as you say, it would be plain stupid to not just use SS. But yeah, looking at that blown-up pic it does look plated. Īnyways, wanted to say that I'll try to have a look again in the morning before I pop in my lenses. I wear contacts for my near-sightedness and seems like I have now lost some range or sorts. I can't actually see stuff very well close up any longer. In fact a plated pin in that location is plain stupid.Īs for the trigger pin, I realized within the last few months or so, that I am getting old. Any pins that reciprocate through rubber seals need to be smooth and stainless steel otherwise if the finish deteriorates then the scars in the plating will tear up the pressure seal and cause leaks. Just looking at your photos if the trigger actuating/transmission pin is plated then that is really bad news. Sporasub by contracting out their gun production basically abdicated their control of the product while pulling in the bigger dollars for what buyers thought were Italian guns. Now the Taiwanese and Chinese often use their “initiative” and make harmless running changes which can be anything but, however there is no way of knowing what the specs really are, or should be. Historically inlet valve bodies in Italian pneumatic guns were chrome plated brass, in fact if you pulled a gun apart the hidden parts of chrome plating often flaked off because they just used flash plating straight onto the brass. I have not looked in the Sporasub manual yet, but the rear handle needs to come off unless you give it a long soak in a tub of freshwater after every use. ![]()
